Computer network is a system which consists of a group of computers connected one another to share information and power. The types of computer network are divided into three parts. They are:

1.Based on the location width

a.LAN (Local Area Network)

This is a local computer network which has very limited area scope. It uses UTP cable or the wireless one. It is usually used in schools, offices, or houses. The advantages of LAN are:

–Parallel use of equipments, such as printer and CPU.

–Easy to share data

–Easier maintenance if the client-server for data management is arranged centered.

b.MAN (Metropolitan Area Network)

This is several LANs which are connected altogether. Media used are wireless and optic fiber. The range scope is around 50 km, depends on what media is used.

c.WAN (Wide Area Network)

This is a group of LAN and MAN which are integrated each other. WAN leads to high-speed data transfer so that it is possible to have faster and more exact communication and data sharing. The association of WAN leads to internet working, which we usually call ‘internet’.

2.Based on the configuration

a.Peer-to-Peer (P2P)

In P2P, each computer has the same position and it does not need a centered system. The advantages are the configuration is easy to make, server computer is not needed, cheap installation budget, and does not need technician with such specific ability. On the contrary, it has lower data security, limited computers, and longer maintenance process.

b.Client/server

It requires a computer which becomes the server to control the network. It has higher data security, unlimited computer quantity, and easier maintenance process. Meanwhile, it also has difficult configuration, expensive installation budget, and needs technician with a specialty.

3.Based on the used media

a.Cable

This is used if the are scope is not too broad. The types of cable used are UTP, optic fiber, and Coaxial.

b.Nircable or wireless

It really assists if it is used in the limited for cables. The media are wireless LAN, infrared, cellphones, satellite, and bluetooth for instance.
